Hey everybody,
I wanted to give you an update on this.
After contacting SAP I go the answer that both SAP ABAP and SAP JAVA do not use this library.
I could confirm this after I have done the search for the vulnerable library.
Please remember that this is not a official statement, that you may not be affected. This is just a hint that we seem to be quite safe using SAP.
In case you want to know if you are affected please open an OSS message at SAP.
Regards,
Niklas
